Gachiiki Chouhatsu Night
"alcohol moves us forward" is how they spent their 1st night together & later how they started dating. pretty cute for 2 grown-ass men.
Ore no Pants ga Hitojichi ni Torarete Imasu
uke blackmailed by seme for coming to school without underwear on. blackmailer/seme gets uke "used" to him so that the uke ends up falling in love because of sex. kinda shity. but they become a "real" couple at the end. weirdness
Hatsujou Kemono Biyori
The Guy I Fell for Is a Wild Beast! -An Arrogant Punk Meets His Match-
Stalker seme & (lesser) stalker delinquent uke<-muscular. seme lures uke into his room filled with posters of the uke & then rapes him. they start dating as a result, but the relationship is still mostly based on sex. no romance, not really anything cute. mostly sex.
The Desire to Kill
Antinomie
lovey ending. unfortunate it near-starts with violation by a rando villain
Rojiura Pussycat
the uke becomes more emotional at the end, but didn't seem to mind getting raped by the seme in ch1 or bothered by much else for that matter. he's pretty fascinating all by himself, but the seme had a very consistent "delinquent" (more like a dark-personality playboy that gets into fights really) character that's just as if not more intriguing than his partner.
